As an FCA-authorised broker that has helped arrange over 800,000 policies, WeCovr knows that navigating private medical insurance in the UK can be complex. One of the most common questions we hear is about cover for pre-existing conditions. This guide provides a clear, comprehensive explanation for you.
Private Medical Insurance (PMI) is designed to give you fast access to high-quality private healthcare for new, treatable medical conditions that arise after your policy begins. This is a crucial point. Standard UK private health cover is specifically for acute conditions, not for managing long-term chronic illnesses or treating health issues you already have.
This guide will break down everything you need to know, including:
In the world of UK private health insurance, a "pre-existing condition" is any disease, illness, or injury for which you have experienced symptoms, received medication, sought advice, or undergone treatment before the start date of your policy.
It doesn't matter whether you received a formal diagnosis or not. If you had symptoms and discussed them with a GP, that counts. Insurers typically look at your medical history from the last five years, but this can vary.
Examples of Pre-Existing Conditions:
The key takeaway is that if the health issue existed in any form before your cover began, it is considered pre-existing.
Understanding the distinction between acute and chronic conditions is fundamental to understanding how PMI works. Insurers build their policies around this difference.
| Feature | Acute Condition | Chronic Condition |
|---|---|---|
| Definition | An illness or injury that is short-lived and likely to respond quickly to treatment, leading to a full or near-full recovery. | A long-term condition that cannot be cured, only managed. It may require ongoing monitoring, medication, or check-ups. |
| Examples | • A broken arm • Appendicitis • Cataracts • A hernia • A curable infection | • Diabetes • Asthma • Arthritis • High blood pressure (hypertension) • Crohn's disease |
| PMI Coverage | This is what PMI is for. Policies are designed to cover the diagnosis and treatment of new acute conditions. | Generally not covered. The day-to-day management of chronic conditions is handled by the NHS. |
Important Note: Some policies may cover an acute flare-up of a chronic condition, but only if that chronic condition was not pre-existing and is eligible for cover under your policy terms. The long-term management of the underlying chronic illness itself remains excluded.
When you apply for private health cover, the insurer needs to assess the risk you pose. This process is called underwriting. For individual PMI policies in the UK, there are two main methods.
This is the most common and straightforward method.
Example: Sarah's Knee Pain Sarah takes out a policy with moratorium underwriting. Three years ago, she had physiotherapy for a sore knee.
This method is more detailed but provides complete clarity from the outset.
| Feature | Moratorium Underwriting | Full Medical Underwriting (FMU) |
|---|---|---|
| Application Process | Quick, no health forms | Longer, requires a full health questionnaire |
| Clarity on Cover | Can be uncertain until a claim is made | Clear and explicit from the start |
| Exclusions | Automatic 5-year look-back, potential to be covered after 2 claim-free years | Specific, named exclusions listed on your policy documents |
| Best For | People with a clean bill of health or those who prefer a quicker setup | People with a complex medical history who want absolute certainty |

This is the million-dollar question. While the general rule is "no," there are specific scenarios where cover might be possible.
Through a Moratorium Policy: As explained above, this is the most common path. If you remain completely symptom-free and require no advice or treatment for a condition for two full years after your policy starts, it may no longer be considered pre-existing.
On a Group Scheme (Workplace PMI): Some large corporate health insurance schemes offer 'Medical History Disregarded' (MHD) underwriting. This is the most comprehensive type of cover, as it ignores pre-existing conditions entirely. However, it is very expensive and rarely available on individual or small business policies.
Switching Insurers with CPME: If you already have private health insurance and want to switch providers, you can often do so on a 'Continued Personal Medical Exclusions' (CPME) basis. This means the new insurer will carry over the same exclusions you had on your old policy. You won't gain cover for pre-existing conditions, but you won't lose the cover you've already built up.
For the vast majority of people buying a new personal policy, any condition that existed in the five years prior will be excluded from day one.
It can be tempting to omit a past health issue from your application, hoping it will go unnoticed. This is a major mistake.
Your insurance policy is a contract based on the principle of "utmost good faith." If you fail to declare something and later make a claim, the insurer has the right to:
When in doubt, declare it. It is far better to have a condition formally excluded than to risk your entire policy.
It's vital to remember that having a pre-existing condition excluded from your PMI policy does not leave you without care. The UK's National Health Service (NHS) provides comprehensive care to all UK residents, free at the point of use.
Your PMI policy and the NHS are designed to work in partnership:
With NHS waiting lists in England involving over 7.5 million treatment pathways (according to NHS England data from 2024), having PMI provides valuable peace of mind and speedy access for new issues that may arise.
Modern private health insurance is about more than just treating illness; it's also about promoting and maintaining good health. Even if you have exclusions for pre-existing conditions, you can still get immense value from the wellness benefits included in many policies.
